Overview
The Universal Standard Section is the core structural module for tower cranes, designed for quick assembly and high load-bearing capacity in construction sites. Engineered to global safety standards, it provides a stable foundation for cranes operating at heights up to 200m, with modular design enabling easy height extension.
Features
Robust Structural Design
Box-type section with welded H-beam columns (section size: 1.6m x 1.6m to 2.5m x 2.5m), capable of withstanding 8,000kN·m overturning moment.
High-strength bolts (10.9 level) with anti-loosening washers, torque-tested to 900N・m to prevent joint failure in seismic zones (PGA=0.3g).
Surface Protection
Two-coat epoxy-polyurethane system (total thickness 150μm), resistant to UV aging (QUV tested for 5,000 hours) and abrasive dust (ISO 12944 C4-H).
Galvanized steel inserts in bolt holes to prevent thread corrosion, extending maintenance intervals by 50%.
Installation Efficiency
Self-aligning guide pins reduce alignment time by 30% during Rising operation，compatible with Zoomlion, Liebherr, and Sany crane models.
Integrated lifting eyes with load ratings (20t-50t) for safe crane handling, marked with clear weight and capacity labels.
Application
High-Rise Construction: Forming the main mast of 600-ton-moment cranes in skyscraper projects (e.g., Dubai Creek Tower, Shanghai Tower).
Infrastructure Projects: Supporting bridge-building cranes in harsh coastal environments (e.g., Hong Kong-Zhuhai-Macao Bridge), with salt-spray-resistant coatings.
Wind Farm Installation: Specialized sections for cranes erecting 12MW offshore turbines, compliant with EN 14439 crane safety standards.
Why Choose Us
Interchangeable Design: Compatible with 95% of global crane brands through standardized bolt patterns (M30-M42), reducing spare parts inventory costs.
Lifecycle Support: Free structural health monitoring (SHM) consultation, using strain gauges to predict section fatigue life (min. 15,000 cycles).
| ①Ladder : A vertical or inclined ladder fixed on the standard section of the tower crane for the operator to safely climb to the operation room at the top of the tower crane or perform maintenance work.
②Safety Cage : A safety facility installed around the ladder, the main function is to prevent the climbing personnel from accidentally falling when working on the tower crane.
③Resting Platform : It is a plane area set on the tower crane for the operator to rest or work, usually located at some intervals of the ladder. |
